Benefits of technology

[0009] The present invention has been achieved in view of the foregoing problems of the prior art. The present invention provides an endoscope light source

Problems solved by technology

Consequently, depending on the type of scope, the light source unit may be excessive in intensity, and also may heat up the ends of the scopes due to the heat components of the illumination light unless the quantity of the light source unit is turned down.
In such a light source unit, pictures (images) of appropriate brightness can be obtained by increasing the electronic shutter speed, whereas an excessively

Embodiment Construction

[0044] Embodiments of the invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of a processor (endoscope light source unit) 10 that contains a power supply unit to which the present invention is applied. FIG. 2 is an abbreviated cross sectional view taken along the II-II line of in FIG. 1, showing essential components of the processor 10.

[0045] The processor 10 is provided on the front thereof (as viewed in FIG. 1) with a scope socket 11 into which a connector 104 of an electronic scope 100 is to be inserted (see FIG. 4), and a scope lock lever 12 for locking the inserted connector 104 so as not to come off. The scope socket 11 establishes connection with connect pins, or the like, provided in the connector 104 of the electronic scope 100. A light guide socket 13 for the light guide connector 115 of the electronic scope 100 (or a fiber scope) to be inserted into is formed below the scope socket 11.

[0046] The processor 10 also has an opera...

Abstract

An endoscope light source unit for making illumination light incident on an incident end face of a light guide connected thereto, includes an aperture device having aperture openings of different opening ratios, for selectively positioning one of the aperture openings between the incident end face of the light guide and the light source; a reading device for reading information on an illumination light quantity limit from a memory provided in a scope connected to the endoscope light source unit; and a controller for selecting an opening ratio of the aperture device in accordance with the information on the illumination light quantity limit read by the reading device, wherein the controller controls the aperture device so as not to position any of the aperture openings, which have an opening ratio higher than the selected opening ratio, between the incident end face of the light guide and the light source.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an endoscope light source unit suitable for an endoscope or an electronic endoscope, etc. [0003] 2. Description of the Related Art [0004] Recent electronic endoscope systems have a processor with a built-in light source unit, to which an electronic scope having an electronic camera mounted on the distal end thereof or a fiber scope for conducting observation only through optical members is connected for use. In particular, electronic scopes have been provided for use with a wide variety of thicknesses and functions suited to different locations of observation. Processors connectable with various types of electronic scopes and fiber scopes must also have light source units that are compatible with such various electronic scopes and fiber scopes. For this reason, conventional light source units have been constructed so as to supply necessary amounts of light to electronic scopes that r...
